Definitions
- the invention relates to a method for checking the adjustment of a headlight in a motor vehicle and to a corresponding device and a corresponding motor vehicle.
- the document EP 2 485 032 A2 describes a method for adjusting a basic setting of a motor vehicle headlamp, in which the position of a light-dark boundary of the light distribution of the headlamp on a measuring surface is detected for different swivel angles of the headlamp light beam and based thereon a correction angle for adjusting the basic adjustment of the headlamp is determined.
- the document EP 2 128 590 A1 discloses a method for calibrating a horizontal light-dark boundary generated by a headlight of a vehicle.
- the light-dark boundary is detected by a camera of the vehicle and a deviation of the actual position from a desired position of the light-dark boundary is determined from the image data.
- the methods known from the prior art have the disadvantage that the corresponding light distribution of the headlight must always be projected onto a planar projection surface in order to check the headlamp setting.
- the methods can thus not be used for arbitrarily shaped or aligned projection surfaces.
- the object of the invention is therefore to provide a method and a device with which the adjustment of the headlight of a motor vehicle can be checked flexibly with different projection surfaces.
- step a) in a predefined basic position of the headlight by means of an image recording device of the motor vehicle, a projection surface facing the headlight is detected at one or more recording times comprising a recording time with the headlight activated.
- the predetermined basic position may be a single, fixed headlight position, unless the motor vehicle has a dependent example of the load condition headlight adjustment. Otherwise, the home position is preferably the position of the headlamp in a state where the vehicle is not loaded.
- step a) image data are obtained with spatial position information, the image data containing the projection surface.
- the image recording device is designed such that it determines three-dimensional spatial position information about the surroundings of the motor vehicle.
- three-dimensional position data are to be understood as positions, in particular the actual or desired position or the predetermined beam path described below.
- TOF Time Of Flight
- the Dolphinnahr e Huawei may also be part of a pattern projection system in which a defined pattern is projected and recorded on the screen. Three-dimensional distance information is determined on the basis of the distortions of the pattern resulting from the recorded images.
- a separate light source may be used to generate the pattern. Nonetheless, the pattern can also be generated by the headlight itself.
- so-called matrix beams also called pixel light
- matrix beams also called pixel light
- a 3D model of the projection surface is determined from the image data obtained in step a), which describes the projection surface in a reference system of the motor vehicle based on a plurality of positions on the surface of the projection surface.
- the creation of appropriate SD Models by means of three-dimensional image data is known per se from the prior art and is therefore not explained in detail.
- An example of a method for forming a 3D model is described in the publication Ahlvers, U., ZOlzer, U.: 3D evaluation of stereo images, Uniaba Helmut Schmidt University, Hamburg, 2005 Edition, Volume 15 described.
- the reference system of the motor vehicle is to be understood as meaning a reference system stationary in the motor vehicle, which moves when the position of the motor vehicle is changed.
- the reference system of the motor vehicle is given by a coordinate system at the installation of the image pickup device.
- a lst T position of a light region within the light distribution of the headlamp is identified on the screen in the reference system of the motor vehicle from the captured through the image pickup means image data, wherein the light range by a predetermined for the basic position of the headlamp beam path in the Light of the headlamp is characterized in the reference system of the motor vehicle.
- the term of the light range is to be understood broadly and may include any characteristic structure, such as a light-dark boundary, or even a predetermined light spot (eg the location with the highest brightness). To identify the light range, known pattern recognition algorithms can be used.
- a desired position of the light region within the light distribution of the headlight on the projection surface in the reference system of the motor vehicle is determined. This determination can easily be made e.g. be done by the piercing points of rays of the beam path are determined by the projection surface described on the 3D model in a conventional manner.
- an adjustment (ie an incorrect setting) of the headlamp is determined if the (absolute) deviation between the actual position and the desired position of the light range exceeds a predetermined threshold.
- the inventive method has the advantage that any projection surfaces can be used to check the headlamp, because in the context of the method, a 3D model of the projection is created. In other words, the projection surface is measured during the process. The process can be carried out very quickly.
- all components for carrying out the method are integrated in the motor vehicle itself, so that it is possible, for example, to check each time a headlight is activated to determine whether it is correctly set.
- the method can be used for any type of motor vehicle headlamps. In particular, thus the setting of a headlight of the motor vehicle, such as a low beam headlamp or a high beam headlamp or fog lamp, be checked.
- the projection surface is detected in step a) at a single recording time when the headlight is activated, whereby the method can be carried out very quickly.
- the projection surface for creating the 3D model is detected when the headlight is not activated or when a special light source is activated, and the light distribution with the headlight activated is recorded again separately on the projection surface.
- the light range in the light distribution of the headlight can be defined differently on the projection surface.
- the light area can represent the location with the highest light intensity.
- a warning message is issued if an adjustment of the headlight is detected in step e).
- this warning message is issued by the motor vehicle warning message, which can be perceived by the driver of the vehicle.
- the warning message is in particular a visual and / or acoustic and / or haptic message. In this way, the driver is informed immediately about an obstructed headlight, so that he can cause a readjustment of the headlight.
- the motor vehicle comprises an automatic adjusting device for adjusting the position of the headlight in the motor vehicle, wherein in a step f), the automatic adjusting device, the position of the headlight corrected for the deviation between the actual position and the target position, if the deviation exceeds the predetermined threshold.
- the automatic adjusting device for adjusting the position of the headlight in the motor vehicle, wherein in a step f), the automatic adjusting device, the position of the headlight corrected for the deviation between the actual position and the target position, if the deviation exceeds the predetermined threshold.
- the headlamp does not have to be switched to its normal operating state when carrying out the method. Rather, the headlight at the or the recording times in step a) flash only briefly.
- a measure of the accuracy of the 3D model is determined in step b).
- the determination of appropriate measures is known per se or is within the scope of expert action. For example, the larger the adjacent surface positions on the projection surface according to the 3D model, the smaller the degree of accuracy becomes.
- the method is aborted or a warning message is issued if the measure of the accuracy of the 3D model is below a predetermined threshold. In this way it is taken into account that under certain circumstances the properties of the projection surface are not suitable for carrying out the method.
- the ambient brightness is determined from the image data obtained in step a), wherein the method is interrupted or a warning message is output when the ambient brightness exceeds a predetermined brightness value.
- a position of a component of the vehicle in particular a position in the front region of the vehicle, such as the engine hood, is extracted from the image data. Based on this information, the reference system of the motor vehicle is then identified in the image data. This ensures the correct position of the reference system in the image data.
- the invention further relates to a device for checking the adjustment of a headlamp in a motor vehicle, the device comprising a computer device which is configured such that with the computer device in their operation, the method according to the invention or one or more preferred Variants of the method according to the invention are feasible.
- the computing device may be implemented by one or more units, e.g.
- the computer device can represent the light control device described below in combination with the evaluation unit.
- the components of the device according to the invention are part of the motor vehicle itself. That is, the invention also includes a motor vehicle, which comprises the device according to the invention for checking a headlamp of the motor vehicle.
- FIG. 1 shows a perspective view of a motor vehicle and a projection surface, with reference to which an embodiment of the method according to the invention is explained;
- Fig. 2 is a schematic representation of the components in a motor vehicle, which are required for carrying out the method according to the invention.
- An embodiment of the method according to the invention is explained below, in which the inspection of the headlamp setting of a motor vehicle is performed by the motor vehicle itself. That is, all components needed to check the headlamp setting are installed in the motor vehicle.
- Fig. 1 shows a perspective view of the front part of a motor vehicle 1 with the two headlights 2 and 3, the setting to be checked. As explained in more detail below, in an adjustment of the headlights and an automatic adjustment of the same can be made by an adjusting device.
- the method can also analogously for checking the high beam setting when activating the high beam and possibly also for other headlights, such as fog lights, can be used.
- Fig. 2 the components shown schematically in Fig. 2 are used in the motor vehicle.
- the two headlights are in Fig. 2 analogous to Fig. 1 denoted by the reference numerals 2 and 3 and connected to a light control unit LS.
- the left-hand headlight 2 can be changed in position by means of motors M1 and M2, the motor M1 moving the headlight in the vertical direction and the motor M2 moving the headlight in the horizontal direction.
- motors M3 and M4 are provided for adjusting the position of the headlamp 3, the motor M3 moving the headlamp in the vertical direction and the motor M4 moving the headlamp in the horizontal direction.
- the motors M1, M2 and M3, M4 each represent an automatic adjusting device for the corresponding headlight 2 or 3.
- a 3D camera in the form of a stereo camera SK is further installed, which at the front edge of the roof is disposed at the position P of the vehicle C (see FIG. 1).
- the stereo camera comprises the two cameras K1 and K2, which record the area in front of the vehicle from different angles and thereby capture a stereo image and thus three-dimensional spatial information as image data.
- the stereo camera SK is connected to an evaluation unit AE in the vehicle, which is a computer unit, which in turn has a connection to the light control unit LS.
- the light control unit LS and the evaluation unit AE may also be integrated with one another and form a common control and evaluation unit.
- the headlight adjustment is started by the driver or the vehicle, for example by entering a corresponding operating command via a user interface by the driver. Subsequently, the light control unit LS moves the headlights 2 and 3 to a current home position which is the position of the headlamp without adjustment due to increased load state of the vehicle. Subsequently, the control unit LS activates the headlight illuminants of the headlights 2 and 3 for generating the low-beam distribution.
- the cameras K1 and K2 of the stereo camera SK take an image, which is sent to the evaluation unit AE.
- a viewing direction ⁇ KR stored in the evaluation unit is defined, which essentially corresponds to the longitudinal direction of the vehicle 1.
- a reference system of the vehicle in the form of the coordinate system shown in Fig. 1 originating in the position P K and the orthogonal axes x, y and z is given by the viewing direction.
- the z-axis corresponds to the viewing direction of the stereo camera SK.
- This reference system is stationary in the motor vehicle, ie it moves with changing the position of the motor vehicle with this.
- beam directions ⁇ SR ⁇ 1 for the headlamp 2 and SR ⁇ for the headlamp 3 are also set for the low beam of the two headlamps.
- the corresponding beams point to the point in the light distribution of the respective headlamp with the highest intensity.
- the two beam directions are stored in the evaluation unit AE with respect to the above-described reference system of the motor vehicle.
- a projection surface PF is further shown in front of the vehicle, which may be an arbitrary object with a planar structure, because the inventive method can use to adjust the headlights arbitrarily shaped projection surfaces PF.
- the point with the highest light intensity in the low-beam distribution with correct adjustment of the headlight 2 on the projection surface PF is denoted by P Ls and represents the desired position of the point with the highest intensity for the low beam distribution of the headlight 2.
- the position P Rs represents the corresponding desired position for the highest intensity point according to the low beam light distribution generated by the headlamp 3.
- the highest brightness positions generally correspond to the center of the light cone generated by the respective headlamps.
- the headlights 2 and 3 are adjusted, so that the actual position P L , the point with the highest brightness for the headlight 2 and, analogously, the actual position P Ri for the point with the highest brightness for the headlight 3 from the corresponding desired positions P Rs or P
- the images captured by the stereo camera SK are transmitted to the evaluation unit AE.
- This evaluation unit calculates, using known algorithms, a 3D model of the surface of the projection surface PF.
- This SD model contains a plurality of positions identified on the surface with three-dimensional spatial coordinates, these coordinates in turn being indicated in the reference system of the vehicle.
- the actual positions P Li and P Ri in the light distribution of the headlamp are determined by the evaluation unit AE.
- known per se pattern recognition algorithms can be used.
- the evaluation unit AE computes the target positions P Ls and Rs P by the intersection points of the corresponding vectors SR ⁇ l and SR ⁇ are determined by the projection area using the 3D model of the projection surface PF. Subsequently, the evaluation unit AE determines the (absolute) difference between the desired position P Ls and the actual position P Li, as well as the (absolute) difference between the desired position P Rs and the actual position P Ri . In the evaluation unit while a threshold value is specified, which describes a tolerance measure for the adjustment of the headlights. If at least one of the deviations determined is greater than the threshold value, an adjustment (ie incorrect setting) of the headlights is detected in the evaluation unit AE. In the case of such an adjustment, the evaluation unit AE calculates corresponding horizontal and vertical adjustment angles of the headlights 2 and 3 from the above deviations between the desired position and the actual position.
- the headlights are then readjusted via the light control device LS by means of the above-described motors M1 to M4, so that the actual positions coincide again with the desired positions.
- a check of the headlights may be carried out again, starting with the acquisition of new images by the stereo camera SK, if necessary, in order to ensure len that the realignment has actually led to the actual positions correspond to the target positions. If necessary, the adjustment can be adjusted again. Finally, if no deviation between the actual positions and nominal positions is detected, the current position of the headlights is permanently stored as a new basic position in the light control unit.
- the headlights do not have to be switched to their normal operating state when taking pictures by the stereo camera, but they can flash only briefly for this purpose.
- the inspection of the headlamps does not require automatic headlamp adjustment, i. E. the method can also be used in a vehicle without an automatic adjustment device. In this case, whenever an adjustment of the headlight is detected by the evaluation unit, a corresponding warning message is issued, with which the driver is informed that the headlights are adjusted and a corresponding service should be performed.
- the evaluation unit can also determine properties of the projection surface PF. For example, if it is determined that the projection surface is rugged (ie there are large differences between adjacent surface coordinates), the operator is informed by means of a user interface that the projection surface is not suitable for checking the adjustment of the headlights and for reliable adjustment of the headlights ,
- the evaluation unit can also determine the ambient brightness by evaluating the camera images. If this is too high, the driver can be informed via an appropriate user interface that the ambient brightness is too high for a reliable inspection or adjustment of the headlight.
- the evaluation unit can extract a position of the vehicle front (eg engine hood) from the image data via a corresponding pattern recognition algorithm. Based on this information, then the line of sight the stereo camera SK are determined. If this line of sight does not correlate with the direction 1 ⁇ R of FIG. 1, this can be taken into account suitably in the evaluation of the images in the context of a correction door. In other words, the reference system of the motor vehicle for which the respective beam directions SRR and S ⁇ R ⁇ are set can be identified in the image data.
- the inspection of a headlamp can be made using a variety of projection surfaces, without the shape, orientation or position of the projection surface are known in advance.
- This is made possible by modeling the surface of the projection surface based on a 3D model, which is generated based on the image data of a stereo camera or another 3D camera.
- the process works very fast and can be done with each activation of the headlamp if necessary.
- the motor vehicle can also carry out an automatic adjustment, provided that a corresponding adjusting device is installed in the vehicle.
- the method according to the invention was carried out by components in a motor vehicle.
- the method can also be performed by a computer outside of the motor vehicle, which controls the stereo camera and the headlights of the motor vehicle and in particular reads out the image data of the camera and processed for checking the headlights.
- a computer outside of the motor vehicle which controls the stereo camera and the headlights of the motor vehicle and in particular reads out the image data of the camera and processed for checking the headlights.
- the components for carrying out the method must be provided in the motor vehicle. Rather, e.g. a motor vehicle workshop have a device for checking the headlight adjustment according to the inventive method.
